William Charles "Bill" Ayers was born December 26, 1944 in a suburb of Chicago. in the 1960's he became deeply involved in Students for a Democratic Society (SDS). The SDS Constitution describes the organization as:
Students for a Democratic Society is an association of young people on the left. It seeks to create a sustained community of educational and political concern: one bringing together liberals and radicals, activists and scholars, students and faculty.
But SDS did not go far enough for Ayers. By 1969, he had become a part of the Weather Underground, a violent offshoot of the SDS with the goal of overthrowing the US government and replacing it with a dictatorship of the proletariat, aka a Marxist regime.
